HTTPError: 502 Server Error: Bad Gateway for url

The bug

Running this workflow I periodically get a 502 Server Error. It seems like an intermittent server-side error since waiting a few seconds and re-running tends to work (v0.9.2)

To Reproduce

python -m hyp3_isce2 ++process insar_tops_burst \
  S1_136231_IW2_20200604T022312_VV_7C85-BURST \
  S1_136231_IW2_20200616T022313_VV_5D11-BURST \
  --looks 20x4 \
  --apply-water-mask False

Actually been getting the same error for about the last hour. Same error if running wget to a burst URL wget https://sentinel1-burst.asf.alaska.edu/S1A_IW_SLC__1SDV_20230703T121403_20230703T121430_049259_05EC58_F9AB/IW1/VV/8.tiff , but I am able to download a burst URL directly from the web GUI in ASF vertex. Not sure how the authentication flow is different for programmatic access...
